3.1Recommendations for KWS600v3/KIRK Repeater Placement

•In large halls, the KWS600v3/repeater (wall) should be installed vertically in the middle of the space below the drop ceiling.

•In corridors, the KWS600v3/repeater (wall) should be installed vertically preferably at corridor intersections where propagation patterns follow the corridor patterns. The KWS600v3/repeater should point towards the corridor and preferably in the middle height between the floor and the actual ceiling. In case there are high objects in the area, the KWS600v3/repeater (wall) should be installed above those objects but still kept distant from the ceiling.

•The repeater (ceiling) should be installed in the middle of corridors and small rooms.

•In multi-story buildings, KWS600v3 and or repeaters may be installed on opposite sides of the floors to take advantage of the floor-to-floor coverage. The coverage design cannot rely entirely on floor-to-floor propagation; each case must be verified due to variations in local attenuation patterns.

•If the building contains a central open space area with windows to the other areas, KWS600v3 and or repeaters may be installed in this open space to provide a good coverage for the rooms in the inner circle on all floors (e.g. hotels).

•If a KWS600v3 and or repeater (wall) hangs vertically on a wall, the RF coverage in front of the KWS600v3 and or repeaters is twice as large as the coverage at the rear.

•KWS600v3 and or repeaters should not be installed near large metallic objects.

•Reinforced concrete structures have a high attenuation factor inside the building. They decrease the RF coverage range of the KWS600v3 and or repeaters and therefore requires a higher number of KWS600v3 and or repeaters in the building. Lighter types of construction require fewer KWS600v3 since attenuation figures are considerably lower.

3.2Deployment of a KIRK Wireless Server 600v3 Multi-Cell

Note: This section only contains deployment information specific to the KWS600v3. For more information about deployment in general, refer to the Deployment Guide accompanying the Deployment Kit. The Deployment Guide provides instructions on how to use the Deployment Kit to determine the most suitable locations for the different radio units.

3.2.1 Sync over Air

As a user moves from one KWS600v3 radio coverage area to another, the call must be handed over to the next radio unit. To create handover between radio units it is necessary to establish synchronization chains. For more information about synchronization chains, refer to “Examples of Synchronization Chains” on page 33. If the synchronization between radio units is lost, then handover is not possible and ongoing calls will be terminated.

Note: Each KWS600v3 must be placed within the radio coverage area of at least one other KWS600v3 or repeater (radio units).
